Q.What else can I do to get my hydrangeas to bloom?
People in my neighborhood have the same soil as I do and yet their hydrangeas bloom year and after year with no effort. I have tried all the normal things, pruning, not pruning, fertilizing with compost. The leaf edges have been turning brown for the past few years, which leads me to believe they need more water. They have been in front of my house for the past 10 years and are partially under an overhang, but I do water them. Please can you help?

You may be lacking phosphorus. If there is a lack of phosphorus in the soil, plants will have little to no blooms. You can either use a phosphorus rich fertilizer or add some bone meal to the soil.
